1 Claim. 1

The invention, in general, relates to means for limiting the swingingmovement of a member in relation to a fixed member, and moreparticularly relates to an improved device for restricting the openingswing of a door or the like.

Heretofore, considerable attention has been devoted to the provision ofdevices for controlling the opening swing of doors or other hingedly;mounted members, largely for the purpose of preventing damage toadjacent walls or articles. Many of these prior devices, presently onthe market, constitute fixed elements secured to the base board of awall to serve as an abutment or stop, to limit the swing of a door andthus prevent damage to a wall from the door knob or other projectingelement on the door. It is obvious that this fixed member can either besecured to a wall or to the door itself and, such devices often includecushioning means as well as interlocking sockets and tongues to effectthe'same result. The principal disadvantages of these prior devices arealmost apparent in that they project into a room or space and hindermovement of articles of furniture, as well as detract from theappearance of the room. The present invention is directed to an improveddevice for limiting the swinging movement of a door which obviates allof the inherent disadvantages of prior devices, and yet per-'- forms itsobjectives effectively.

A primary object of the invention is to provide an improved door checkfor application to a conventional hinge to limit the swinging movementof a door.

Another important object of the present invention is to provide animproved door check ofthe indicated nature which is additionallycharacterized by its simplicity of construction, its ease of applicationto a conventional door hinge, and its inexpensiveness of production.

A still further object of the invention is to provide an improved doorcheck of the aforementloned character which can be readily applied to aconventional door hinge by the unskilled as well as the skilled.

Other objects of the invention, together with some of its advantageousfeatures, will appear from the following description of a preferredembodiment thereof. It is to be understood, however, that I am not to belimited to the precise embodiment shown, as my invention, as defined inthe appended claim, can be embodied in a plurality and variety of forms.

Referring to the drawings:

Fig. 1 is a perspective view, in development, of two similar elementsconstituting the principal 2 elements of the preferred embodiment of myinvention.

Fig. 2 is a perspective view of the preferred embodiment of myinvention, with the conventional hinge omitted, illustrating the angularrelationship in which the two elements shown in Fig. 1 are'assembled andinterlocked.

Fig, 3 is adevelopment of the preferred embodiment of the presentinvention illustrating the mode of application thereof to a conventionaldoor hinge. vFig. 4 is a longitudinal, fragmentary cross sectionalviewof the preferred embodiment of my invention in operative position on thetop of a conventional hinge.

In its preferred form, the improved door check of my present inventionpreferably comprises, in combination with a hinge, a pair of similarsheets, each having a relatively large opening at one extremity thereoffor passing the pintle of the hinge, as well as a plurality of aperturestherein arranged around said relatively large hole, to-' gether with apin for adjustably fitting any selected pair of registered apertures ofsaid sheets to variably secure said sheets together in various angularrelationships; said connected sheets being interposed between oneenlarged end of the pintle of a hinge and the plates of the hinge. h Asparticularly illustrated in Figs. 1 and 2 of the annexed drawings, Iprovide a pair of similarly constructed and shaped sheets II and I2,which preferably are fabricated from a light weight metal, such aaluminum or a relatively thin section brass, but which can be fabricatedof any other desired material. Each of the sheets I land [2 convenientlyare stamped from such selected material, and it is apparent that one diewill serve for the stamping out of the two sheets. As shown, each ofthese sheets is formed to a generally rectangular configuration,although it is not es-.

sential that the sheets be in such configuration, and in order to avoidany possible damage to the door jamb or wall in which my improved doorcheck ha been applied, is hung or hingedly mounted, I preferably formthe end l3 of each of these sheets to an arcuate shape. Moreover, inorder to avoid any likelihood of damage to a wall adjacent to the doorupon the hinge of which my improved door check has been mounted, theopposite end [4 of each of the sheets H and I2 are conveniently lined orprovided with a cushioning element l6, such as soft rubber which can becemented to the sheets readily.

In accordance with my invention, means are provided in each of thesheets I l and I2 for seat- 3 ing the sheets adjacent to the top or tothe bottom of the pintle II of a conventional or standard type hinge,generally designated by the reference numeral I8 in the accompanyingdrawings and consisting of a pair of opposed plates I9 and 20, havingsuitable apertures 2I therein for fastenin the plates to a door and adoor jamb. As is well known, the pintle I! of a conventional hinge isscrew threaded at the top and bottom thereof for threadedly receivingornamental top and bottom members 22 and 23, respectively. Moreover,these means afford the seating of the sheets II and I2 in operativeposition in any selective one of a plurality of angular relationshipsone to the other. To this end, each of the sheets I I and I2 is formedwith a relatively large opening 26 adjacent one longitudinal extremitythereof for passing the pintle pin I! of the hinge I8, as well as with aplurality of relatively small apertures 21 arranged in circularformation about the large opening 26, and spaced apart as shown. Inaddition, I provide a relatively small pin 28, having a flat head 29 ofsomewhat larger diameter than the diameter of the shank of the pin whichmay be passed through aligned or registered apertures 21 when the twosheets II and I2 are arranged in superposed relationship, and theapertures 21 of one sheet are placed in registry with the apertures 21of the other sheet. It is obvious that the sheets II and I2 can bepreliminarily arranged in any desired angular relationship one toanother, and the pin 28 then passed through aligned apertures 21 of thetwo sheets with the head 29 of the pin seating upon the top sheet of thepair of assembled sheets. Thereafter, the two connected sheets I I andI2, arranged as aforesaid in angular relationship are mounted upon thetop of the hinge I8, with the upper portion of the pintle I'I protrudingthrough the aligned large openings 26 of the two assembled sheets I Iand I2. To complete the assembly or placement of the door check of thepresent improvement in operative position, it is only necessary to screwthe top ornamental knob of the pintle upon the upper threaded portion ofthe pintle. Reference is made to Fig. 3 of the accompanying drawingswhich illustrate. in development, the foregoing steps of mounting theconnected sheets I I and I2 upon the pintle I! of the hinge and at thetop of the hinge.

In Fig. 4 of the annexed drawings, I have illustrated my improved doorcheck in operative position on a conventional hinge, and this viewillustrates the end III of one of the plates bearing against a walladjacent to the door upon which the hinge containing my improved doorcheck is mounted, thus limiting the opening swing of the door.

Inasmuch as the two sheets II and I2 can readily and inexpensively bestamped from suitable material by the use of a single die, and theopening 26 as well as apertures 21 punched from the material in a singleoperation, it is apparent that the cost of producing the sheets II andI2 is relatively nominal. It is also to be noted that there are butthree simple steps for the housewife or any artisan to perform inmounting the door check in operative position, namely, removing theupper knob of the pintle I'I, arranging the sheets I I and I2 in thedesired angular relationship, and connecting the same by the use of thesmall pin '29, and then mounting the same on the top of the pintle andreplacing the top ornamental knob of the pintle by screwing the same onto the upper threaded portion of the pintle. I have successfully appliedmy improved door check to a number of door hinges, and have found thatit effectively limits the swing of the door, without damaging theadjacent wall in which the door is hung.

It is to be understood that the appended claim is to be accorded a rangeof equivalents commensurate in scope with the advance made over theprior art.

I claim:

A door check comprising a hinge, including a pair of hinge platespivotally mounted on a pintle pin and a knob removably secured to thetop of the pintle pin, a pair of similar plates removably mounted onsaid pintle pin between said knob and. the top edges of said hingeplates, each of said pair of similar plates having an openingtherethrough for passing said pintle pin as well as having aperturestherethrough, and an escutcheon pin piercing such apertures forretaining said pair of similar plates on said pintle pin in any selectedone of a plurality of angularly related positions.
